Advancements in Wireless Technology for Single Unit Electrophysiology Recording

Advancements in Wireless Technology for Single Unit Electrophysiology Recording

DATE: TUESDAY, DEC 12, 2017

TIME: 11:00 AM – 12:00 PM EST (UTC -5)

Experts discuss new configurable wireless technologies for single unit electrophysiology recording in small and large animals, with a focus on applications, methodology, data outcomes, and the impact these devices will have in research involving untethered, naturally behaving subjects.

In this webinar sponsored by Neuralynx, Casey Stengel will discuss Cube2: an all-in-one, wireless headstage and data acquisition system for neuronal research in freely moving, untethered subjects. He will explain how Cube2 has been purpose built to enable the study of small animals in social and complex maze environments, by allowing multiple transmitters in the same area, pulling data to local drives. Casey will also review Cube2’s customizable Analog Front End (AFE) interface, and present how it enables the user to optimize weight distribution, record from multiple implant sites, adapt to varying channel counts, and integrate additional animal physiology sensors.

Following, Dr. John Wolf will present case studies and share data from his research focused on long term chronic affects of Traumatic Brain Injury (TBI), including the development of post-traumatic epilepsy (PTE). In order to develop a wireless system for chronically implantable electrodes in a large animal PTE model, Dr. Wolf worked with Neuralynx to develop an enclosure that can be mounted on the animal in its home cage (or behavioral space), and that can record from 64 channels over a period of 24 hours. Dr. Wolf will also present preliminary data from similar studies where he is employing Cube2 for multichannel recordings in rodents.

Attendees will leave this webinar with a better understanding of:

  • How to successfully record data on multiple channels over long time periods
  • How to integrate neural recordings with additional animal physiology sensors
  • The benefits of using wireless headstage systems in social and complex environments
  • How Cube2 is enabling new experimental paradigms that until now were simply not possible

Presenters:

Kari Hoffman, PhD

Associate Professor of Psychological Sciences
Vanderbilt University

Dr. Kari Hoffman is an Associate Professor in Psychological Sciences at Vanderbilt University. She received her PhD in Neuroscience from the University of Arizona, where her work pioneered chronically implanted multi-electrode arrays enabling high-density (576-electrode) recordings of neural populations in the macaque monkey. During her post-doctoral fellowship at the Max Planck Institute in Germany, she used multi-channel neuronal recordings in conjunction with non-invasive imaging techniques to understand the neural basis of face processing and multisensory integration. Her lab at York University in Toronto, Ontario is focused on discovering the dynamics and mechanisms of plasticity in neural ensembles during perception and memory in macaques. She is continuing this work in her new lab at Vanderbilt University. Dr. Hoffman has been recognized by the Alfred P. Sloan Foundation, the Ontario Ministry of Research and Innovation, the Alzheimer’s Association, and the Alzheimer’s Society (Canada), and she is leading a 5-site Brain Canada Multi-Investigator Research Initiative to modify neural dynamics in memory-related brain structures.

John A. Wolf, PhD

Assistant Professor of Neurosurgery
University of Pennsylvania

John’s laboratory focuses on the effects of traumatic brain injury on the limbic system, including the hippocampus, PFC, and amygdala. They are particularly interested in the changes in coding in these structures, as well as the interactions between them, in both cognition and emotional processing. John and his team of researchers are developing new targets of neuromodulation for these regions and their connections as well.
